If three resistors of 20, 60, and 120 ohms are connected in parallel with a current flow of 60 A, what will the applied voltage be?

To determine the applied voltage in a parallel resistor circuit, you first need to calculate the equivalent resistance of the three resistors. In a parallel circuit, the formula for total or equivalent resistance (R_eq) is given by:

1/R_eq = 1/R1 + 1/R2 + 1/R3

For the resistors with values of 20 ohms, 60 ohms, and 120 ohms, this calculation would look like:

1/R_eq = 1/20 + 1/60 + 1/120

Finding a common denominator (which is 120 in this case), we can rewrite each fraction:

1/20 = 6/120,

1/60 = 2/120,

1/120 = 1/120.

Now we can sum these values:

1/R_eq = 6/120 + 2/120 + 1/120 = 9/120.

This simplifies to:

R_eq = 120/9 = 13.33 ohms.

Next, we use Ohm's Law to find the voltage (V) across the equivalent resistance with the given total current (I = 60 A). Ohm's Law states:

V = I *
